JOHN J. OAVAGNARQQF New Your, MACHINE FOR MAKING WATERED SILK- To all whom it may concern- Be it known that I, J OHNJ CAVAGNARO, a

, citizen of the United States, residing in the city, county, andState of New York, and

whose address is 215 Center street, in said 7 city, county, and State, have invented a new and useful Improvement in Machines for Making Watered Silk; and I do hereby declare that the following is a full, clear, and exact desoription of the same. o

My invention is an improvement in machines for making watered silk, in which the woven silk is passed between pressurerolls, one of which is enerally of metal engraved with a number offine longitudinal ribs corresponding to the transverse ribs of the silk and the other of which is usually of compressed paper on which is ,formed by the metal r0 1 a like number of longitudinal indentations, which cooperate with those on the metal roll to upset the ribs of the silk and produce the irregular pattern called water- 1n ot er pressure-roll, usually of metal, having the same number of ribs, which mesh into the ribs of the paper roll, and thus keeps them fresh and in form. I

My improvement consists mainly in a novel combination and arrangement of the 'metal and paper rolls and in the means for vention. Fig. 2 is a side elevation o the same.

3 is the frame of the machine; 4, the standards of the frame. 5 represents bearings fixed at the top of the standards 4. In the bearings 5 is mounted to revolve a horizontal shaft 6 on which is fixed a roll 7, which is usually made of a number of paper disks united under hydraulic pressure and turned down to form a paper roll, which will take and keep the impressions from the engraved metal rolls hereinafter described. On the shaft 6 of the paper im ression-roll 7 is keyed a large spur-wheel 8, which is geared to a small'spur- Wheel 9, which is fixed on a shaft 10, mounted in suitable bearings in the frame 3, which Specification of Letters latente Application filed November 2%}, 1905- Serial No. 289.412.

Against the paper roll also bears an rateaaaruae 1e, teea shaft 10 is driven by a ulley and belt, o as o ratate the paper r01 7 v at the r quired spee l I Beneath and parallel to the impressiomroll 7 is arranged a metalCforming-roll 11 is engraved with a number of fine longitudinalribs 12, corresponding exactly to the transverse ribs in the woven silk to be given the watered effect. 1 The en raved metal forming-roll 11 is hollow and isieated by 118 flame of a Bunsen burner 3, entering i em:

al y atone end. The me a forming r ll .11 is mounted to revolve freely 01.1 Ollkbefilings 14, carried by main bearings 15, Whiflh are mounted to Slide vertically on vertical guides 16 on the frame 3. The bearings 15 are carried by a transverse oke 17, formed on the plunger 18 of an or -inary hydraulic press 19, provided with an accumulator 2.0, by means of which hydraulic press the engraved forming-'roll'll canbe pressed upward against the paper roll 7 and held in suchposition under any desired pressure, but yieldingly, to accommodate varlations in the thickness of the silk. 21 to be watered,which passes between the metal forming-roll 11 and the paper roll 7, as indicated'in thedrawings. The forming-roll 11 bearing with such pressureagainst and rotating with the engraved rotating paper roll-7 produces thereon ribs corresponding exactly to the ribs on the forming-roll 1 1, which ribs, both corresponding to the ribs on the woven silk, cooperate 'to upset, as it were, the ribs on the silk in an i'rregular pattern, producing on both sides of the silk the desired lustrous watered effect.

At the side of the paper roll 7 I arrange an other metal re-formlng-roll 22, engraved like the forming-roll 1 1 and heated likewise interiorly by an axially-entering Bunsen burner 23. 1 The re-forming-roll 22 is mounted to ro- 1 tate freely on roller-bearings 24, carried by main bearings 25, which are mounted to slide horizontally to and from the paper roll 7 in horizontal guides 26 on the frame 3 andis adjustable to any desired degree of against the paper roll 7 by means of orizonta'l hand-screws 27, working in threaded bearings 28 on the frame 3'against the adjustable I bearings 25. The heated engraved re-formressure ing-roll 22, having the same number of ribs as the forming-roll 11, rotating," with and bearing with such pressure against the paper roll, its ribs mesh with the ribs produced on the paper roll 7 by the forming-roll 11 and freshen and re-form the ribson the paper roll.

As the pressure of the forming-roll 11 on the ment of the ressure of the forming-roll is inde- 4 pendent of t e pressure of the reforming-roll, y which independent adjustment of the pressure of the forming and re-forming rolls I am enabled to produce watered silk of much greater luster and beauty of pattern on both faces, with much greater ease and convenience than with machines commonly employed heretofore.

Having thus described my invention and the mode in which I carry it into practice, I claim as my invention 1. In a machine for making Watered silk, the, combination with the frame, the impression-roll and means for rotating the same, of rotatable forming and re-forming rolls having ribs thereon, and means for pressing the forming and re-forming rolls against the impression-roll independently of each other and in different planes.

2. In a machine for making Watered silk, the combination with the frame, the impression-rolland means for rotating the same, of a rotatable forming-roll having ribs thereon, and means for pressing the same yieldingly against the impression-roll in one plane, a rotatable re-forming-roll having ribs corresponding to those on the forming-roll, and means for pressing the re-forming-roll adjustably against the impression-roll in a plane different from that of the forming-roll.

3. In a machine for making watered silk, the combination with the frame, the impression-roll and means for rotating the same, of

a rotatable forming-roll having movable bear ings, an hydraulic press for pressing the forming-roll upward against the under side of the impression-roll a rotatable re-forming-roll, having movable bearings, the forming and re-forming rolls having ribs thereon, and means for adjusting the bearings of the reforming-roll against the side of the impressionroll.

In testimony whereof I have hereunto set my hand the 6th day of November, 1905.
